Cougar v. Wolf

Wolves and cougars are increasingly at war because wolf packs continue to multiply and spread into parts of the Rocky Mountains dominated for decades by cougars. Now, big cat wrangler Boone Smith tracks the most recent wolf and cat skirmishes as he delves into why these two big predators carry on the cats vs. dogs rivalry. Boone's goal is to pinpoint the places where cougar-wolf conflicts most often occur by gathering clues about each creature's hunting, feeding and fighting behaviors. (Source: National Geographic Wild)
